LCDI Power Cord and Plug
This air conditioner is equipped with an LCDI (Leakage Current Detection and Interruption) power cord that is required
by UL. This power supply cord contains state-of-the-art electronics that sense leakage current. If the cord is damaged

The test and reset buttons on the LCDI Plug are used to check if the plug is functioning properly. To test the plug:
1. Plug power cord into a grounded 3 prong outlet
2. Press RESET (on some units a green light will turn on).
3. Press the TEST Button, the circuit should trip and cut all power to the air conditioner (on some units a green light
may turn off.
4. Press the RESET button for use. You will hear a click and the A/C is not ready for use.
NOTES:
• The RESET button must be engaged for proper use.
• The power supply cord must be replaced if it fails to trip when the TEST button is pressed and the unit fails to reset. •
Do not use the power supply cord as an ON/OFF switch. The
power supply cord is designed as a protection device.
• A damaged power supply cord must be replaced with a new
power supply cord from Thermocore Powered by Gree.
• The power supply cord contains new user serviceable parts.
Opening the tamper-resistant case voids all warranty and per-
formance claims.

INSTALLATION & ASSEMBLY INSTRUCTIONS
Window Preparation
Please read all instructions prior to installing your air conditioner. Two people are recommended to install this product. If
a new electrical outlet is required, have the outlet installed by a qualified electrician before installing the unit.
Before installing the unit, check the dimensions of your window to make sure the air conditioner will fit. This unit is made
to fit inside a standard double-hung window. Make sure the window is in good shape and able to firmly hold the needed
screws. If not, make repairs prior to installing the unit.
Storm Window Requirements
A storm window frame will not allow the air conditioner to tilt properly which in turn will keep it from draining properly. To
adjust for this, attach a board or piece of wood to the sill. The board or wood piece should have a depth of at least 1 1/2”.
Make sure the board or piece of wood is approximately 1/2” higher than the storm window frame. This will allow the air
conditioner to tilt enough for proper drainage. (See FIG. 2).
Prior to Installing the Air Conditioner
1. Check for anything that could block airflow. Check the area outside of the window for things such as shrubs, trees, or
awnings. Check the inside area to make sure curtains, drapes, or blinds will not prevent proper airflow.
2. Check the available electrical outlet. The power supply must be the same as shown on the unit serial nameplate
(located on the left side of the unit, near the front faceplate). Be sure the outlet is close enough for the power cord to
reach.
3. Carefully unpack the air conditioner. Remove all packing material and make sure the floor is protected when remov-
ing. Due to the large size of this air conditioner, two people should move the unit together.
